Watch Mariah Carey Perform "Vision of Love" and "Infinity" on 'Jimmy Kimmel Live'

Mariah Carey sings despite bronchitis.

Mariah Carey won't let a dodgy throat ruin the show for her fans.

The pop legend shook off a bout of bronchitis to perform something old, and something new, overnight on Jimmy Kimmel Live.

Carey repeated her feat from the Billboard Music Awards by sharing a medley of her 1990 hit "Vision of Love" with her new number "Infinity."

The veteran artist canceled a performance in Las Vegas last week due to illness, just days after she started a high profile residency. Watch her performance below.
